In the manual of this device I found out that the only way to get new firmware installed is via a Windows PC. The reason I got this box is bacause it runs XUbuntu. I use (X)Ubuntu on all my computers. No need for Windows. So I was stuned by this finding...

How can I put in new firmware in this box using Ubuntu Linux?? Every (X)Ubuntu user knows it is not wise to update to a new version by upgrading.

For those not so familiar to (X)Ubuntu, find a offical ubunto forum; xubuntu.org/help/

I've also attached the source for rkflashtool.c if someone else cares to try building it against their linux machine and libusb there.

It appears to issue the magic formula to control the flash memory space, and requests the offset and size, then reads from std input (file device 0) or write to std output (file device 1). I just don't know what the offset and size should be to flash my RK902
